A corvette ZR1 can brake to a stop from 60mph in 2.6 seconds. If the car has a weight of 3225 pounds, what force (in Newtons) acts on the car? 

I got -15122.3N

Speed of car=60 mph=26.82 m/s

Mass of car=3225 lb=1462.835 kg

Let force be F.

F=change in momentum/time

  =m(v2-v1)/t

  =1462.835*(0-26.82)/2.6

  =-15090 N
